A broadband download limit is a cap on the amount of data that can be downloaded from the internet using a broadband connection within a specific period, usually a month. The internet service provider typically sets the download limit which varies depending on the broadband plan.

Once the download limit is reached, the internet speed may be reduced, or additional fees may be charged for further data usage. Download limits are designed to prevent excessive or abusive use of the network that can negatively impact other customers' experience and to ensure that the network is used reasonably and efficiently.

It's important to check the download limit and any associated fees or speed reductions when selecting a broadband plan to ensure that it meets your needs and budget. Some broadband plans may offer unlimited data usage or higher download limits for an additional fee.
